Can't re-edit ammo information? – Applied Ballistics Review

This app has the most confusing interface that I have ever seen in on the App Store. After painstakingly entering the data, having to constantly look up the unique terms on the company's web site, I can't edit my current ammo library to change my zero settings. There are plenty of other ballistic apps the use mostly the same open source ballistic calculator that are easier to use, have a better interface, are much better organized, and are cheaper and just as accurate out to 1000 yards! This app was a waste of money as far as I'm concerned. I was conned by the paid internet reviews.
